[SPARK-15814][SQL] Aggregator can return null result

## What changes were proposed in this pull request?

It's similar to the bug fixed in https://github.com/apache/spark/pull/13425, we should consider null object and wrap the `CreateStruct` with `If` to do null check.

This PR also improves the test framework to test the objects of `Dataset[T]` directly, instead of calling `toDF` and compare the rows.

## How was this patch tested?

new test in `DatasetAggregatorSuite`
